Silver lining of the pandemic...
NASA researchers found that since February, pandemic restrictions have reduced global nitrogen dioxide (an air pollutant from fossil fuel combustion) concentrations by nearly 20%.

3) “The model simulation and machine learning analysis took place at the NASA Center for Climate Simulation. Its “business as usual” scenario showed an alternate reality version of 2020—one that did not experience any unexpected changes in human behavior brought on by pandemic.
4) “The researchers received data from 46 countries—a total of 5,756 observation sites on the ground—relaying hourly atmospheric composition measurements in near-real time. On a city-level, 50 of the 61 analyzed cities show nitrogen dioxide reductions between 20-50%.
5) Wuhan was the first city reporting an outbreak of COVID-19. It was also the first to show reduced nitrogen dioxide emissions—60% lower than simulated values expected. A 60% decrease in Milan & a 45% decrease in NYC followed shortly, as local restrictions went into effect.”
